Pac-Man Museum features 9^[b] games from the Pac-Man series, ranging from the original maze games, puzzle games and platformers. Each game is based on their original arcade/console release (Pac-Attack is based on the Genesis/Mega Drive version, while Pac-Man Arrangement is based on its Namco Museum Battle Collection port). Additional features in the compilation include a special guide mode for Pac-Man, online and offline leaderboards, and achievements (console versions only).

The game also features an award system for each game (minus Ms. Pac-Man) called the Stampbook. Completing an achievement adds a stamp to the Stampbook (with each stamp representing the bonus fruits from the original Pac-Man). There are 8 stamps to fill for each game, with medals being awarded to the player for completing each game. Additionally, filling in a stamp adds a character or object from Pac-Man and the Ghostly Adventures to the Pac-Room (which is also displayed in the main menu), where the player can view Pac-Man's apartment from the TV series and view all obtained characters and items. These items range from characters from the series (like Pac-Man and the Ghosts), objects (including a Pac-Man's Arcade Party machine), and figurines based on the characters (as well as Galaga cameos). As well as being able to view close-ups of the characters and objects, they are also accessible through the game's Item List, which also displays information regarding each item or character.

Pac-Man Museum received a score of 66/100 on Metacritic, a score of 6/10 on Steam, and Hardcore Gamer gave the game a 4/5, calling it "the best representation of what has been a truly illustrious video game career."^[2]

Destructoid gave the game a 7/10 rating, saying "Pac-Man Museum has a bunch of middling pieces, but the addition of Battle Royale is the icing on the cake. If you've never played Championship Edition before and thus do not have DX to compare it to, it's a perfect way to re-acclimate yourself to the franchise, while you use Royale to spice up your next local gathering. Everyone else who lacks friends on-hand or has already played CE should wait for a sale, or pass this one up entirely."
